Question

Equivalent resistance of resistors in series increases while in case of parallel, equivalent resistance decreases. Explain why?

Answer 1

Explanation:

because in case of series current remain same due to which resistance increases but in parallel current get divided and resistance decreases

Answer 2

in parallel resistors have equal voltage as of equivalent resistance

And current increases in equivalent resistance because in parallel current divides

V= IR

Voltage same

Current more

So Resistance has to decrease

In series

voltage splits and current same

V= IR

V and R proportional

Voltage in equivalent becomes more So Resistance will be more
